Retrieve a tensor by record ID.
AI agents call get_tensor to retrieve information from Tensorus MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data from a tensor database using a record identifier. It performs a query-like operation with no ability to modify, delete, or execute code. The blast radius of misuse is minimal — at worst, an agent could read tensors it shouldn't have access to, which is a confidentiality concern rather than an integrity or operational risk. Severity is low because retrieval alone cannot damage data or systems.
From the tool's definition Tool name is 'get_tensor' and description states 'Retrieve a tensor by record ID' — a pure read operation with no modifications, deletions, or side effects.
Attacks that exploit this kind of access
Retrieve a tensor by record ID. It is categorised as a Read tool in the Tensorus MCP MCP Server, which means it retrieves data without modifying state.
Register the Tensorus MCP server in PolicyLayer and add a rule for get_tensor: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Tensorus MCP. Nothing to install.
get_tensor is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_tensor rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_tensor. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_tensor is provided by the Tensorus MCP server (tensorus/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
